There is nothing that brightens up a house nor adds seasonal value quite like the addition of a sunroom. Sunrooms extend the enjoyment of the outdoors, while protecting the home owner from weather extremes. Most builders and installers of sunrooms estimate the average cost to be $80 to $170 per square foot, but such prices are not set in stone.
Prices vary from region to region and can change based on proximity to the manufacturer, price fluctuations in overall material costs, and cost for installation.
Another factor that can affect the overall average price of a sunroom is choice of material. Tempered glass verses glazed plastics will be more expensive but will offer a greater durability and protection from the weather.
Types of insulation can also adjust the cost of a sunroom. This being the case, it is always a good idea to use the best insulation you can afford.
Overall, since most sunrooms range in size from 50 to 100 square feet, expect your investment to be between $4000 on the lower end of the price scale up to $17,000 for the larger, more expensive sunrooms.
